1.Go to the RBA’s ‘Cash rate target’ web page at www.rba.gov.au/statistics/cash-rate and to the Trading Economics ‘Australian dollar’ web page at www.tradingeconomics.com/australia/currency . Compare the RBS’s target cash rate decisions with the value of the Australian dollar at the time of each decision since February 2013. What does this tell us about the relationship between interest rates and foreign exchange rates? (Hint: Set the graph of exchange rates to a line graph with a moving average.)
